Dust Off West Coast of Africa - September 18th, 2010

For the last few days, a thick cloud of dust has been seen blowing over the Ras Nouadhibou Peninsula of Morocco/Western Sahara and Mauritania and out over the Atlantic Ocean (click here for previous article).

Here, the dust can be seen blowing southwestward towards a low pressure system located a couple hundred miles west of the
Cape Verde Archipelago. Both the full extent of the dust plume and the area of low pressure are best observed in the full image.

The system is moving westward at 5 to 10 mph. Thunderstorm activity has increased during the past few hours and environmental conditions are gradually becoming more favorable for additional development of this disturbance. There is a medium chance (40 percent) of this system becoming a tropical cyclone during the next 48 hours.
